Disaggregated die with input/output (i/o) tiles

ABSTRACT

Embodiments may relate to a die with a processor. The die may include a first input/output (I/O) tile adjacent to a first side of the processor, and a second I/O tile adjacent to a second side of the processor. The first or second I/O tiles may be communicatively coupled with the processor. Other embodiments may be described or claimed.

BACKGROUND

Typically, in legacy dies, die size may be based on the area required to support the core logic. A die that is subject to this limitation may be referred to a core-limited die. Alternatively, die size may be based on the die perimeter necessary to support breakout of the input/output (I/O) of the die. A die that is subject to this limitation may be referred to as an I/O-limited die. In legacy dies, the die size may generally be based on the larger of the die size that results from a core-limitation or an I/O-limitation.

However, I/O-limited die may have an increased area because of the I/O of the die. This increased area may result in underutilized transistor area at or near the region of the core logic. This increase in die size may negatively impact the number of dies that may be manufactured per wafer, and may also significantly increase the cost of products that use the resultant die.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings which form a part hereof, wherein like numerals designate like parts throughout, and in which is shown by way of illustration embodiments in which the subject matter of the present disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. Therefore, the following detailed description is not to be taken in a limiting sense.

For the purposes of the present disclosure, the phrase “A or B” means (A), (B), or (A and B). For the purposes of the present disclosure, the phrase “A, B, or C” means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

The description may use perspective-based descriptions such as top/bottom, in/out, over/under, and the like. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of embodiments described herein to any particular orientation.

The description may use the phrases “in an embodiment,” or “in embodiments,” which may each refer to one or more of the same or different embodiments. Furthermore, the terms “comprising,” “including,” “having,” and the like, as used with respect to embodiments of the present disclosure, are synonymous.

The term “coupled with,” along with its derivatives, may be used herein. “Coupled” may mean one or more of the following. “Coupled” may mean that two or more elements are in direct physical or electrical contact. However, “coupled” may also mean that two or more elements indirectly contact each other, but yet still cooperate or interact with each other, and may mean that one or more other elements are coupled or connected between the elements that are said to be coupled with each other. The term “directly coupled” may mean that two or elements are in direct contact.

In various embodiments, the phrase “a first feature [[formed/deposited/disposed/etc.]] on a second feature,” may mean that the first feature is formed/deposited/disposed/etc. over the feature layer, and at least a part of the first feature may be in direct contact (e.g., direct physical or electrical contact) or indirect contact (e.g., having one or more other features between the first feature and the second feature) with at least a part of the second feature.

Various operations may be described as multiple discrete operations in turn, in a manner that is most helpful in understanding the claimed subject matter. However, the order of description should not be construed as to imply that these operations are necessarily order dependent.

Embodiments herein may be described with respect to various Figures. Unless explicitly stated, the dimensions of the Figures are intended to be simplified illustrative examples, rather than depictions of relative dimensions. For example, various lengths/widths/heights of elements in the Figures may not be drawn to scale unless indicated otherwise. Additionally, some schematic illustrations of example structures of various devices and assemblies described herein may be shown with precise right angles and straight lines, but it is to be understood that such schematic illustrations may not reflect real-life process limitations which may cause the features to not look so “ideal” when any of the structures described herein are examined, e.g., using scanning electron microscopy (SEM) images or transmission electron microscope (TEM) images. In such images of real structures, possible processing defects could also be visible, e.g., not-perfectly straight edges of materials, tapered vias or other openings, inadvertent rounding of corners or variations in thicknesses of different material layers, occasional screw, edge, or combination dislocations within the crystalline region, and/or occasional dislocation defects of single atoms or clusters of atoms. There may be other defects not listed here but that are common within the field of device fabrication.

As noted above, legacy die sizes may typically be referred to as core-limited or 110-limited. However, 110-limited die may have an increased die area because of the I/O of the die, which may result in underutilized transistor area at or near the region of the core logic. New silicon processes typically enable aggressive scaling for core area but I/O scaling typically does not scale at the same rate. This relationship can create problems for keeping a good balance of core-limited or I/O-limited die size optimization.

Embodiments herein relate to the use of die disaggregation techniques to decouple the core die area from the I/O perimeter requirement by creating a die complex where the I/O may extend beyond the footprint of the main die. Specifically, the die perimeter utilized for I/O escape may not be constrained by a rectangular shape. In some embodiments, this disaggregation technique may include the use of a bridge such as an embedded multi-die interconnect bridge (EMIB) a silicon interposer, an integrated fan-out on a substrate, or with a memory on the substrate, etc. to create or enable the offset I/O tile die complex. It will be understood these are examples of such bridges, and other types or kinds of bridges may be used in other embodiments.

Embodiments may provide a number of advantages. For example, the offset I/O tile concept may enable active die area reduction for die complexes that would otherwise be I/O-limited in legacy configurations. By disaggregating the I/O on a die, the I/O tile may be instanced multiple times and utilized across multiple programs. The offset tile configuration may further decouple the I/O tile perimeter requirement from the perimeter available on the main die, which may extend the ability to reuse that tile across different die complexes.

FIG. 1 depicts an example of a die configuration with a plurality of I/O tiles, in accordance with various embodiments. Specifically, FIG. 1 depicts a die configuration 100 a which may be similar to a legacy configuration. Specifically, an I/O structure 105 may generally surround a processor 110. In various embodiments, the processor 110 may be a stand-alone processor, a central processing unit (CPU), a general processing unit (GPU), a core of a single or multi-core processor, a logic circuit, or some other type of processor. The I/O structure 105 may be communicatively coupled with the processor 110 by one or more physical or electronic couplings (not shown) such as a bridge, an interposer, etc. Generally, the I/O structure 105 and the processor 110 may be considered elements of a single die. However, as may be seen, the I/O structure 105 may be significantly larger than the processor 110 because it may be desirable for the I/O structure 105 to include additional input or output pins or ports, which may dictate the size of the I/O structure 105. The discrepancy in sizes between the processor 110 and the I/O structure 105 may result in underutilized area 103 between the I/O structure 105 and the processor 110 as described above.

However, the I/O structure 105 may be separated into a plurality of I/O tiles and rearranged to form a disaggregated die complex as shown in die configuration 100 b. Specifically, the I/O structure 105 may be split along the dashed lines to form four I/O tiles 105 a, 105 b, 105 c, and 105 d (collectively referred to herein as “I/O tiles 105 a-105 d”). The I/O tiles 105 a-105 d may be rearranged around the processor 110 as shown in die configuration 100 b. It will be noted that although the I/O tiles 105 a-105 d may have the same total I/O breakout area as the I/O structure 105, the underutilized area 103 may be eliminated in the die configuration 100 b. As such, the die configuration 100 b may be viewed as more compact and take up less overall space than the die configuration 100 a, which may provide more space for the addition or inclusion of other elements that would otherwise be prohibited by the presence of the underutilized area 103.

FIG. 2 depicts a top-down view of an example die 200 with a plurality of I/O tiles, in accordance with various embodiments. The die 200 may include a processor 210, which may be similar to, and share one or more characteristics with, processor 110. The die 200 may further include a number of I/O tiles 205 a/205 b/205 c/205 d (collectively referred to herein as “I/O tiles 205 a-205 d”) which may be similar to, and share one or more characteristics with, I/O tiles 105 a-105 d.

The I/O tiles 205 a-205 d may be implemented as separate physical elements such as a chip or a tile on the die 200. Specifically, the die 200 may include a substrate 220 which may be formed of a substrate material such as an organic or inorganic material, a silicon or silicon-including material, or some other type of substrate material. The substrate 220 may include one or more layers of substrate material and may be cored or coreless. In some embodiments, the substrate 220 may include one or more conductive elements such as traces, striplines, microstrips, vias, pads, etc. which may enable, facilitate, or otherwise be part of an electrical or communicative pathway between two elements of the die 200 or of an element of the die 200 and another element of an electronic device of which the die 200 is a part. In some embodiments, the substrate 220 may be considered to be a passive interposer, an active interposer, or some other type of substrate or element.

The processor 210 and the I/O tiles 205 a-205 d may be coupled with the substrate 220, for example by solder bumps, pins, or some other type of interconnect element. The substrate 220 may further include one or more bridges 215 a/215 b/215 c/215 d (collectively referred to herein as “bridges 215 a-215 d”). In some embodiments, one or more of the bridges 215 a-215 d may be a bridge such as an active or passive EMIB. Additionally or alternatively, one or more of the bridges 215 a-215 d may be a silicon bridge, a conductive trace such as a trace, a microstrip, or a stripline, an integrated fan-out on the substrate 220, a fan-out with a memory on the substrate 220, or some other type of bridge.

FIG. 3 depicts a cutaway view of the example die 200 of FIG. 2, in accordance with various embodiments. Specifically, FIG. 3 depicts a cutaway view along line A-A′ of the die 200 of FIG. 2. As may be seen, one or more of the bridges 215 a-215 d may be embedded within the substrate 220 as shown in FIG. 3 with respect to bridge 215 b. In other embodiments one or more of the bridges 215 a-215 d may be coupled to a same face of the substrate 220, may only be partially embedded within the substrate 220, may be embedded at a deeper layer of the substrate 220 and coupled with the processor 210 or an I/O tile by one or more vias, etc.

As may be seen in FIGS. 2 and 3, the processor 210 and the I/O tiles 205 a-205 d may overlap one or more of the bridges 215 a-215 d. This overlap may be because the bridges 215 a-215 d may communicatively couple the processor 210 to the I/O tiles 205 a-205 d. As such, signals to or from the processor 210 may pass through the I/O tiles 205 a-205 d and the bridges 215 a-215 d, thereby allowing I/O breakout on the die 200.

FIGS. 4-6 depict alternative examples of a die configuration with a plurality of I/O tiles, in accordance with various embodiments. Generally, the Figures are depicted as simplified examples of the configuration of a processor and an I/O tile. Not depicted in FIGS. 4-6 for the sake of lack of redundancy are a substrate such as substrate 220. Additionally, not depicted in FIGS. 4 and 5 for the sake of lack of redundancy are bridges such as bridges 215 a-215 d.

Specifically, FIG. 4 may include a die configuration 400 which may depict a processor 410 and I/O tiles 405 a, 405 b, 405 c, and 405 d (collectively referred to herein as “I/O tiles 405 a-405 d”). The processor 410 may be similar to, and share one or more characteristics with, processor 110. The I/O tiles 405 a-405 d may be generally similar to, and share one or more characteristics with, I/O tiles 105 a-105 d. However, as may be seen in FIG. 4, one or more of the I/O tiles 105 a-105 d may have a different size than another of the I/O tiles 105 a-105 d. Specifically, as may be seen, I/O tiles 405 b and 405 d may be larger than I/O tiles 405 a and 405 c. The specific size or configuration of respective ones of the I/O tiles of embodiments herein may be based on a variety of factors such as manufacturing considerations, whether several I/O breakouts need to be adjacent to one another, the specific configuration of a processor or the die substrate, or other factors.

In some embodiments, a die may include a plurality of processors, and the processors and I/O tiles may be patterned on the die. FIG. 5 depicts an example of such patterning. Specifically, FIG. 5 depicts a die configuration 500 that includes a plurality of processors 510 a, 510 b, 510 c, and 510 d (collectively referred to herein as “processors 510 a-510 d”). Respective ones of the processors 510 a-510 d may be similar to, and share one or more characteristics with, processor 110. The die configuration 500 may further include a plurality of I/O tiles 505 a, 505 b, 505 c, 505 d (collectively referred to herein as “I/O tiles 505 a-505 d”). The I/O tiles 505 a-505 d may be similar to, and share one or more characteristics with, I/O tiles 205 a-205 d. It will be understood that each of the I/O tiles in FIG. 5 may not be specifically enumerated for the sake of lack of clutter of the Figure.

In general, it may be seen that the die configuration 500 may be a repeating pattern of the die configuration 100 b. It will be recognized that although the pattern is only repeated four times, in other embodiments the pattern may be repeated more or fewer times than depicted. In some embodiments, the pattern may involve repeating instance of different die configurations (e.g., the die configuration of FIG. 4 may be repeated with the die configuration 100 b, etc.).

In some embodiments, an I/O tile may be communicatively coupled with a plurality of processors. Such an embodiment is shown in the die configuration 600 of FIG. 6. Specifically, FIG. 6 depicts an alternative example of a die configuration 600 with a plurality of I/O tiles, in accordance with various embodiments.

The die configuration 600 may include a plurality of processors 610 a and 610 b, which may be respectively similar to, and share one or more characteristics with, processor 110. The die configuration 600 may further include a plurality of I/O tiles 605 a, 605 b, 605 c, 605 d, 605 e, and 605 f (collectively “I/O tiles 605 a-605 f”) which may be respectively similar to, and share one or more characteristics with, one or more of I/O tiles 105 a-105 d. The die configuration 600 may further include bridges 615 a and 615 b, which may be respectively similar to, and share one or more characteristics with, one of bridges 215 a-215 d.

As can be seen, bridges 615 a and 615 b may be respectively coupled with processors 610 a and 610 b. Additionally, bridges 615 a and 615 b may both be coupled with I/O tile 605 f. In this way, I/O tile 605 f may serve as an I/O breakout for both processors 610 a and 610 b.

In some embodiments, a plurality of processors may be present on a die, and the processors may be coupled with one another and share an I/O breakout. Such an embodiment is shown in the die configuration 1100 of FIG. 11. Specifically, FIG. 11 depicts an alternative example of a die configuration 1100 with a plurality of I/O tiles, in accordance with various embodiments.

The die configuration 1100 may include a plurality of processors 1110 a, 1110 b, and 1110 c, which may be respectively similar to, and share one or more characteristics with, processor 110. The die configuration 1100 may further include a plurality of I/O tiles 1105 a, 1105 b, 1105 c, 1105 d, 1105 e, 1105 f, 1105 g, and 1105 h (collectively, “I/O tiles 1105 a-1105 h”) which may be respectively similar to, and share one or more characteristics with, one or more of I/O tiles 105 a-105 d. The die configuration 1100 may further include bridges 1115 a, 1115 b, 1115 c, and 1115 d (collectively, “bridges 1115 a-1115 d”) which may be respectively similar to, and share one or more characteristics with, one of bridges 215 a-215 d.

As can be seen, bridge 1115 b may be communicatively coupled with both processor 1110 b and 1110 a. Similarly, bridge 1115 c may be communicatively coupled with both processor 1110 b and 1110 c. Processor 1110 a may be communicatively coupled with I/O tile 1105 a by bridge 1115 a. Similarly, processor 1110 c may be communicatively coupled with I/O tile 1105 e by bridge 1115 d. In some embodiments, each of the bridges 1115 a-1115 d may be of the same size or type as each other, while in other embodiments one or more of the bridges 1115 a-1115 d may be of a different size or type than another of the bridges 1115 a-1115 d.

As shown in FIG. 11, processor 1110 b may not be directly coupled with an I/O tile by a bridge. Rather, processor 1110 b may be communicatively coupled with an I/O tile such as I/O tiles 1105 a or 1105 e through a communicative path that includes another processor and various bridges. For example, processor 1110 b may be communicatively coupled with I/O tile 1105 a through a communicative path that includes processor 1110 a and bridges 1115 a/1115 b. Additionally or alternatively, processor 1110 b may be communicatively coupled with I/O tile 1105 e through a communicative path that includes processor 1110 c and bridges 1115 c/1115 d. However, it will be recognized that in other embodiments processor 1110 b may further be coupled with one of I/O tiles 1105 a-1105 h by a bridge such as one of bridges 1115 a-1115 d or some other type of bridge discussed herein.

It will be noted that in the die configurations 400/500/600 the various I/O tiles are depicted as directly adjacent to the various processors, as opposed to being spaced apart as shown in, for example, FIG. 1 or 2 or FIG. 11. It will be understood that the spacing of the I/O tiles from the processors in the various embodiments may be based on factors such as available die area, the specific elements or materials used, how the processor(s) are coupled with the I/O tiles, etc.

Additionally, it will be understood that the depicted configurations are intended as example embodiments to illustrate various concepts, and other embodiments may vary. For example, the specific size, shape, orientation, or number of elements may be different in different embodiments. Aspects of some embodiments may be combined with one another. In some embodiments, certain elements that are depicted as identical may vary from one another. For example, in embodiments with a plurality of bridges (e.g., bridges 615 a and 615 b), the bridges may be of a different type, size, bandwidth, configuration, etc. than one another. Similarly, in embodiments with a plurality of processors (e.g., processors 610 a and 610 b), the processors may be of a different type or size than one another (e.g., one could be a logic while the other is a memory, or some other configuration). Other variations may be present in other embodiments.

FIG. 7 depicts an example technique for the manufacture of a die with a plurality of I/O tiles, in accordance with various embodiments. The technique may be described herein with respect to elements of FIGS. 2 and 3, however it will be understood that the technique may be applicable, in whole or in part, with or without modification, to other embodiments of the present disclosure.

The technique may include coupling, at 705, a processor with a substrate. The substrate may be similar to, for example, substrate 220. The processor may be similar to, for example, processor 210. Coupling of the processor with the substrate may be done using interconnects such as a solder bump, a solder ball of a ball grid array (BGA), a pin of a pin grid array (PGA), or some other type of interconnect. In some embodiments, the interconnects may be coupled with a conductive element of the substrate or the processor such as a pad or some other conductive element.

The technique may further include coupling, at 710, a first I/O tile with the substrate. The I/O tile may be coupled with the substrate adjacent to a first side of the processor. The I/O tile may be similar to, for example, one of I/O tiles 205 a-205 d. Similarly to element 705, the I/O tile may be coupled with the substrate using an interconnect such as a BGA, a PGA, or some other type of interconnect.

The technique may further include coupling, at 715, a second I/O tile with the substrate adjacent to a second side of the processor. The second I/O tile may be similar to, for example, one of I/O tiles 205 a-205 d. Similarly to elements 705 or 710, the second I/O tile may be coupled with the substrate using an interconnect such as a BGA, a PGA, or some other type of interconnect.

The technique may further include communicatively coupling, at 720, the first I/O tile with the processor. Specifically, the I/O tile and the processor may be communicatively coupled by a bridge such as one of bridges 215 a-215 d which may be, for example, an EMIB, a conductive trace, a silicon bridge, or some other type of bridge.

The technique may further include coupling, at 725, the second I/O tile with the processor. Similarly to element 720, the second I/O tile and the processor may be communicatively coupled by a bridge such as one of bridges 215 a-215 d as described above.

It will be understood that the technique of FIG. 7 is intended as a highly simplified example technique, and other embodiments may include one or more variations from the technique described in FIG. 7. For example, in some embodiments certain elements may be performed in a different order than depicted, or concurrently with one another. For example, elements 710 and 715, or 720 and 725, may be performed concurrently. In some embodiments, certain elements (such as element 705) may not be present, whereas in other embodiments the technique may include additional elements. Other variations may be present in other embodiments.

FIG. 8 is a top view of a wafer 1500 and dies 1502 that may include one or more I/O tiles, or may be included in an IC package including one or more dies with one or more I/O tiles in accordance with various embodiments. The wafer 1500 may be composed of semiconductor material and may include one or more dies 1502 having IC structures formed on a surface of the wafer 1500. Each of the dies 1502 may be a repeating unit of a semiconductor product that includes a suitable IC. After the fabrication of the semiconductor product is complete, the wafer 1500 may undergo a singulation process in which the dies 1502 are separated from one another to provide discrete “chips” of the semiconductor product. The die 1502 may include one or more I/O tiles, one or more transistors or supporting circuitry to route electrical signals to the transistors, or some other IC component. In some embodiments, the wafer 1500 or the die 1502 may include a memory device (e.g., a random-access memory (RAM) device, such as a static RAM (SRAM) device, a magnetic RAM (MRAM) device, a resistive RAM (RRAM) device, a conductive-bridging RAM (CBRAM) device, etc.), a logic device (e.g., an AND, OR, NAND, or NOR gate), or any other suitable circuit element. Multiple ones of these devices may be combined on a single die 1502. For example, a memory array formed by multiple memory devices may be formed on a same die 1502 as a processing device (e.g., the processing device 1802 of FIG. 10) or other logic that is configured to store information in the memory devices or execute instructions stored in the memory array.

FIG. 9 is a side, cross-sectional view of an IC device assembly 1700 that may include one or more IC packages or other electronic components (e.g., a die) including one or more I/O tiles, in accordance with any of the embodiments disclosed herein. The IC device assembly 1700 includes a number of components disposed on a circuit board 1702 (which may be, e.g., a motherboard). The IC device assembly 1700 includes components disposed on a first face 1740 of the circuit board 1702 and an opposing second face 1742 of the circuit board 1702; generally, components may be disposed on one or both faces 1740 and 1742.

In some embodiments, the circuit board 1702 may be a printed circuit board (PCB) including multiple metal layers separated from one another by layers of dielectric material and interconnected by electrically conductive vias. Any one or more of the metal layers may be formed in a desired circuit pattern to route electrical signals (optionally in conjunction with other metal layers) between the components coupled to the circuit board 1702. In other embodiments, the circuit board 1702 may be a non-PCB substrate.

The IC device assembly 1700 illustrated in FIG. 9 includes a package-on-interposer structure 1736 coupled to the first face 1740 of the circuit board 1702 by coupling components 1716. The coupling components 1716 may electrically and mechanically couple the package-on-interposer structure 1736 to the circuit board 1702, and may include solder balls (as shown in FIG. 9), male and female portions of a socket, an adhesive, an underfill material, and/or any other suitable electrical and/or mechanical coupling structure.

The package-on-interposer structure 1736 may include an IC package 1720 coupled to a package interposer 1704 by coupling components 1718. The coupling components 1718 may take any suitable form for the application, such as the forms discussed above with reference to the coupling components 1716. Although a single IC package 1720 is shown in FIG. 9, multiple IC packages may be coupled to the package interposer 1704; indeed, additional interposers may be coupled to the package interposer 1704. The package interposer 1704 may provide an intervening substrate used to bridge the circuit board 1702 and the IC package 1720. The IC package 1720 may be or include, for example, a die (the die 1502 of FIG. 8), an IC device, or any other suitable component. Generally, the package interposer 1704 may spread a connection to a wider pitch or reroute a connection to a different connection. For example, the package interposer 1704 may couple the IC package 1720 (e.g., a die) to a set of BGA conductive contacts of the coupling components 1716 for coupling to the circuit board 1702. In the embodiment illustrated in FIG. 9, the IC package 1720 and the circuit board 1702 are attached to opposing sides of the package interposer 1704; in other embodiments, the IC package 1720 and the circuit board 1702 may be attached to a same side of the package interposer 1704. In some embodiments, three or more components may be interconnected by way of the package interposer 1704.

In some embodiments, the package interposer 1704 may be formed as a PCB, including multiple metal layers separated from one another by layers of dielectric material and interconnected by electrically conductive vias. In some embodiments, the package interposer 1704 may be formed of an epoxy resin, a fiberglass-reinforced epoxy resin, an epoxy resin with inorganic fillers, a ceramic material, or a polymer material such as polyimide. In some embodiments, the package interposer 1704 may be formed of alternate rigid or flexible materials that may include the same materials described above for use in a semiconductor substrate, such as silicon, germanium, and other group III-V and group IV materials.
